The process equipment was designed to handle the auto refrigeration of the Anhydrous Ammonia. RE: Strength & Properties of ASTM A36 Steel at 40FInconsistent notch toughness on thicker plate sections.1Please elaborate. The situation is: I have a fabricator who is supposed to U stamp an aqua ammonia tank which is specified at 40F ambient temperature operations. There is no doubt I will reject the design. I understand that ASTM AS36 is OK down to 20F but I don't know how bad it is at 40F with shell thickness 3/8" and heads thickness 5/16" Thanks for further explanation.1SamCheung, What is the design MDMT of the tank? What are the rated MDMT of the shell and head?1Sam Metengr gave you the correct answer.you just do not understand it. Do you know what these terms mean ? Where is your tank located ? Has that area ever experienced 40F ? API650 contains a section about the selection of materials based on the geographic area. Materials are grouped base on thier notchtoughness. Are you aware of the fact that tank shell temperature never mimic the instantaeuos air temperatures ? Is this the first tank material you have ever evalated ? MJCThanks for responding. Vender: 110F; MDMT: 20F At 25 PSI Specified: 110F; MDMT: 40F at 30 PSI My main concern is how bad is it from 20F to 40F if the tank were put into service. What will be the result and any documentation or real experience to put the tank in prolong period of 40F ambient temperature operation.SamCheung; You need to Review ASME B&PV Code, Section VIII, Div 1, Part UCS. There are materials listed, and impact curves, and material that is not permitted. You need to familiarize your self with Section VIII for pressure retaining [email protected] MJCronin, 1. You are right I have no idea at all. Can you explain in real layman terms. 2. The tank will experience 40F. 3. What is the notch toughness at 20F and what is the notch toughness at 40F for SA36? Why notch toughness at 40F is not acceptable? Thanks for any further [email protected] metengr, I have 2 copies of ASME besides me. I read the ASME 2 days ago. I am a bit dum, but that does not address my question how bad it is at 40F or what is bad about the SA36 at 40F. Will you please elaborate? [email protected], How thick is thick? > 0.394" on CD curves? That was for impact testing exemption, right?SamCheung; A36 is typically not used as pressure retaining material for low temperature service, for the reason I stated above in my first response. ASME Sa 36 is permitted under strict limitations. You are not dumb, you just don't have the experience to understand Code rules. Please review the specific sections below; ASME Section VIII, Div 1, Part UCS UCS6 Steel Plates . Your answer is there for using A 36 plate in a pressure vessel service. UCS65 and UCS66.

A36 Steel Properties at High Temperatures | Hunker

A36 is a mild steel used in many applications. A36 steel has a carbon content of only .26 percent, classifying it as a lowcarbon steel. Other elements in the alloy include manganese (.75 percent), sulfur (less than .05 percent) and phosphorous (less than .04 percent).

ASTM Standard A36. A36 steel can maintain its strength at temperatures ranging up to 650°F. This metal is excellent for welding and produces high quality welded joints. While A36 is a strong material, it is more easily bent than materials such as C1018 steel, as it has less yield strength.
